Devices, methods, and graphical user interfaces for media playback control using intensity-based user inputs

ABSTRACT

A method is performed at an electronic device. While media is playing, the device detects a contact at a touch-sensitive surface location associated with a first media playback control. If the device is operating in a first media playback mode, the device performs a media playback operation associated with the first media playback control when a characteristic intensity of the contact remains below a first intensity threshold. If the device is operating in a second media playback mode, and a characteristic intensity of the contact exceeds the first intensity threshold, the device performs the media playback operation associated with the first media playback control. If the device is operating in the second media playback mode and the characteristic intensity of the contact remains below the first intensity threshold, the device continues playing the media on the device without performing the media playback operation associated with the first media playback control.

RELATED APPLICATION

This application claims priority to U.S. Provisional Application Ser.No. 62/399,185, filed Sep. 23, 2016, which is incorporated by referenceherein in its entirety.

TECHNICAL FIELD

This relates generally to electronic devices with touch-sensitivesurfaces, including but not limited to electronic devices withtouch-sensitive surfaces that control media playback.

BACKGROUND

The use of touch-sensitive surfaces as input devices for computers andother electronic computing devices has increased significantly in recentyears. Exemplary touch-sensitive surfaces include touchpads andtouch-screen displays. Such surfaces are widely used to manipulate userinterfaces on a display.

For example, some electronic devices use touchpads or touch-screendisplays to manipulate media playback controls in a user interface.Conventional electronic devices, however, control media playback inlimited, inefficient, and frustrating ways. Some devices only allowusers to navigate media via a single user interface. In addition, somedevices require a user to seek out and visually identify an iconrepresenting a particular transport control (e.g., a play, pause, fastforward, or skip to next media item icon) on the screen, before tappingthe icon to perform that transport control. If the user was performinganother activity (such as walking, running, or having a conversation),the user needs to interrupt their activity and focus exclusively on thescreen to control playback of the media, thereby breaking the user'sconcentration on their activity. This change is focus distracts the userfrom performing other activities.

SUMMARY

Accordingly, there is a need for electronic devices with faster, moreefficient methods and interfaces for controlling media playback. Suchmethods and interfaces optionally complement or replace conventionalmethods for controlling media playback. Such methods and interfacesreduce the number, extent, and/or nature of the inputs from a user andproduce a more efficient human-machine interface. For battery-operateddevices, such methods and interfaces conserve power and increase thetime between battery charges.

DESCRIPTION OF EMBODIMENTS

In light of the deficiencies with conventional media player userinterfaces, there is a need for electronic devices with more effectivemethods and interfaces for controlling media playback. Described hereinare methods that enable a user to control music playback with force orpressure based inputs, without needing to look at the screen. Suchmethods and interfaces optionally complement or replace conventionalmethods for controlling media playback. Such methods and interfacesreduce the number, extent, and/or nature of the inputs from a user andproduce a more efficient human-machine interface (e.g., bydisassociating transport control icons from inputs). Further, suchmethods conserve power (thereby increasing the time between batterycharges), reduce unnecessary/extraneous/repetitive inputs, andpotentially reduce memory usage.

Similarly, the phrase “if it is determined” or“if [a stated condition or event] is detected” is, optionally, construedto mean “upon determining” or “in response to determining” or “upondetecting [the stated condition or event]” or “in response to detecting[the stated condition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, andassociated processes for using such devices are described. In someembodiments, the device is a portable communications device, such as amobile telephone, that also contains other functions, such as PDA and/ormusic player functions. Example embodiments of portable multifunctiondevices include, without limitation, the iPhone®, iPod Touch®, and iPad®devices from Apple Inc. of Cupertino, Calif. Other portable electronicdevices, such as laptops or tablet computers with touch-sensitivesurfaces (e.g., touch-screen displays and/or touchpads), are,optionally, used. It should also be understood that, in someembodiments, the device is not a portable communications device, but isa desktop computer with a touch-sensitive surface (e.g., a touch-screendisplay and/or a touchpad).

In the discussion that follows, an electronic device that includes adisplay and a touch-sensitive surface is described. It should beunderstood, however, that the electronic device optionally includes oneor more other physical user-interface devices, such as a physicalkeyboard, a mouse and/or a joystick.

The device typically supports a variety of applications, such as one ormore of the following: a note taking application, a drawing application,a presentation application, a word processing application, a websitecreation application, a disk authoring application, a spreadsheetapplication, a gaming application, a telephone application, a videoconferencing application, an e-mail application, an instant messagingapplication, a workout support application, a photo managementapplication, a digital camera application, a digital video cameraapplication, a web browsing application, a digital music playerapplication, and/or a digital video player application.

The various applications that are executed on the device optionally useat least one common physical user-interface device, such as thetouch-sensitive surface. One or more functions of the touch-sensitivesurface as well as corresponding information displayed on the deviceare, optionally, adjusted and/or varied from one application to the nextand/or within a respective application. In this way, a common physicalarchitecture (such as the touch-sensitive surface) of the deviceoptionally supports the variety of applications with user interfacesthat are intuitive and transparent to the user.

Attention is now directed toward embodiments of portable devices withtouch-sensitive displays. FIG. 1A is a block diagram illustratingportable multifunction device 100 with touch-sensitive display system112 in accordance with some embodiments. Touch-sensitive display system112 is sometimes called a “touch screen” for convenience, and issometimes simply called a touch-sensitive display. Device 100 includesmemory 102 (which optionally includes one or more computer readablestorage mediums), memory controller 122, one or more processing units(CPUs) 120, peripherals interface 118, RF circuitry 108, audio circuitry110, speaker 111, microphone 113, input/output (I/O) subsystem 106,other input or control devices 116, and external port 124. Device 100optionally includes one or more optical sensors 164. Device 100optionally includes one or more intensity sensors 165 for detectingintensity of contacts on device 100 (e.g., a touch-sensitive surfacesuch as touch-sensitive display system 112 of device 100). Device 100optionally includes one or more tactile output generators 167 forgenerating tactile outputs on device 100 (e.g., generating tactileoutputs on a touch-sensitive surface such as touch-sensitive displaysystem 112 of device 100 or touchpad 355 of device 300). Thesecomponents optionally communicate over one or more communication busesor signal lines 103.

As used in the specification and claims, the term “tactile output”refers to physical displacement of a device relative to a previousposition of the device, physical displacement of a component (e.g., atouch-sensitive surface) of a device relative to another component(e.g., housing) of the device, or displacement of the component relativeto a center of mass of the device that will be detected by a user withthe user's sense of touch. For example, in situations where the deviceor the component of the device is in contact with a surface of a userthat is sensitive to touch (e.g., a finger, palm, or other part of auser's hand), the tactile output generated by the physical displacementwill be interpreted by the user as a tactile sensation corresponding toa perceived change in physical characteristics of the device or thecomponent of the device. For example, movement of a touch-sensitivesurface (e.g., a touch-sensitive display or trackpad) is, optionally,interpreted by the user as a “down click” or “up click” of a physicalactuator button. In some cases, a user will feel a tactile sensationsuch as an “down click” or “up click” even when there is no movement ofa physical actuator button associated with the touch-sensitive surfacethat is physically pressed (e.g., displaced) by the user's movements. Asanother example, movement of the touch-sensitive surface is, optionally,interpreted or sensed by the user as “roughness” of the touch-sensitivesurface, even when there is no change in smoothness of thetouch-sensitive surface. While such interpretations of touch by a userwill be subject to the individualized sensory perceptions of the user,there are many sensory perceptions of touch that are common to a largemajority of users. Thus, when a tactile output is described ascorresponding to a particular sensory perception of a user (e.g., an “upclick,” a “down click,” “roughness”), unless otherwise stated, thegenerated tactile output corresponds to physical displacement of thedevice or a component thereof that will generate the described sensoryperception for a typical (or average) user.

The visual output optionally includes graphics, text, icons,video, and any combination thereof (collectively termed “graphics”). Insome embodiments, some or all of the visual output corresponds to userinterface objects. As used herein, the term “affordance” refers to auser-interactive graphical user interface object (e.g., a graphical userinterface object that is configured to respond to inputs directed towardthe graphical user interface object). Examples of user-interactivegraphical user interface objects include, without limitation, a button,slider, icon, selectable menu item, switch, hyperlink, or other userinterface control.

Touch-sensitive display system 112 has a touch-sensitive surface, sensoror set of sensors that accepts input from the user based on hapticand/or tactile contact. Touch-sensitive display system 112 and displaycontroller 156 (along with any associated modules and/or sets ofinstructions in memory 102) detect contact (and any movement or breakingof the contact) on touch-sensitive display system 112 and converts thedetected contact into interaction with user-interface objects (e.g., oneor more soft keys, icons, web pages or images) that are displayed ontouch-sensitive display system 112. In an example embodiment, a point ofcontact between touch-sensitive display system 112 and the usercorresponds to a finger of the user or a stylus.

In some embodiments, the user interface is designed towork with finger-based contacts and gestures, which can be less precisethan stylus-based input due to the larger area of contact of a finger onthe touch screen. In some embodiments, the device translates the roughfinger-based input into a precise pointer/cursor position or command forperforming the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100optionally includes a touchpad (not shown) for activating ordeactivating particular functions. In some embodiments, the touchpad isa touch-sensitive area of the device that, unlike the touch screen, doesnot display visual output.

Each of the above identified modules and applications correspond to aset of executable instructions for performing one or more functionsdescribed above and the methods described in this application (e.g., thecomputer-implemented methods and other information processing methodsdescribed herein). These modules (i.e., sets of instructions) need notbe implemented as separate software programs, procedures or modules, andthus various subsets of these modules are, optionally, combined orotherwise re-arranged in various embodiments. In some embodiments,memory 102 optionally stores a subset of the modules and data structuresidentified above. Furthermore, memory 102 optionally stores additionalmodules and data structures not described above.

In some embodiments, device 100 is a device where operation of apredefined set of functions on the device is performed exclusivelythrough a touch screen and/or a touchpad. By using a touch screen and/ora touchpad as the primary input control device for operation of device100, the number of physical input control devices (such as push buttons,dials, and the like) on device 100 is, optionally, reduced.

The predefined set of functions that are performed exclusively through atouch screen and/or a touchpad optionally include navigation betweenuser interfaces. In some embodiments, the touchpad, when touched by theuser, navigates device 100 to a main, home, or root menu from any userinterface that is displayed on device 100. In such embodiments, a “menubutton” is implemented using a touchpad. In some other embodiments, themenu button is a physical push button or other physical input controldevice instead of a touchpad.

FIG. 1B is a block diagram illustrating example components for eventhandling in accordance with some embodiments. In some embodiments,memory 102 (in FIG. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g.,in operating system 126) and a respective application 136-1 (e.g., anyof the aforementioned applications 136, 137-155, 380-390).

Event sorter 170 receives event information and determines theapplication 136-1 and application view 191 of application 136-1 to whichto deliver the event information. Event sorter 170 includes eventmonitor 171 and event dispatcher module 174. In some embodiments,application 136-1 includes application internal state 192, whichindicates the current application view(s) displayed on touch-sensitivedisplay system 112 when the application is active or executing. In someembodiments, device/global internal state 157 is used by event sorter170 to determine which application(s) is (are) currently active, andapplication internal state 192 is used by event sorter 170 to determineapplication views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additionalinformation, such as one or more of: resume information to be used whenapplication 136-1 resumes execution, user interface state informationthat indicates information being displayed or that is ready for displayby application 136-1, a state queue for enabling the user to go back toa prior state or view of application 136-1, and a redo/undo queue ofprevious actions taken by the user.

Event monitor 171 receives event information from peripherals interface118. Event information includes information about a sub-event (e.g., auser touch on touch-sensitive display system 112, as part of amulti-touch gesture). Peripherals interface 118 transmits information itreceives from I/O subsystem 106 or a sensor, such as proximity sensor166, accelerometer(s) 168, and/or microphone 113 (through audiocircuitry 110). Information that peripherals interface 118 receives fromI/O subsystem 106 includes information from touch-sensitive displaysystem 112 or a touch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripheralsinterface 118 at predetermined intervals. In response, peripheralsinterface 118 transmits event information. In other embodiments,peripheral interface 118 transmits event information only when there isa significant event (e.g., receiving an input above a predeterminednoise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit viewdetermination module 172 and/or an active event recognizer determinationmodule 173.

Hit view determination module 172 provides software procedures fordetermining where a sub-event has taken place within one or more views,when touch-sensitive display system 112 displays more than one view.Views are made up of controls and other elements that a user can see onthe display.

Another aspect of the user interface associated with an application is aset of views, sometimes herein called application views or userinterface windows, in which information is displayed and touch-basedgestures occur. The application views (of a respective application) inwhich a touch is detected optionally correspond to programmatic levelswithin a programmatic or view hierarchy of the application. For example,the lowest level view in which a touch is detected is, optionally,called the hit view, and the set of events that are recognized as properinputs are, optionally, determined based, at least in part, on the hitview of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related tosub-events of a touch-based gesture. When an application has multipleviews organized in a hierarchy, hit view determination module 172identifies a hit view as the lowest view in the hierarchy which shouldhandle the sub-event. In most circumstances, the hit view is the lowestlevel view in which an initiating sub-event occurs (i.e., the firstsub-event in the sequence of sub-events that form an event or potentialevent). Once the hit view is identified by the hit view determinationmodule, the hit view typically receives all sub-events related to thesame touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which viewor views within a view hierarchy should receive a particular sequence ofsub-events. In some embodiments, active event recognizer determinationmodule 173 determines that only the hit view should receive a particularsequence of sub-events. In other embodiments, active event recognizerdetermination module 173 determines that all views that include thephysical location of a sub-event are actively involved views, andtherefore determines that all actively involved views should receive aparticular sequence of sub-events. In other embodiments, even if touchsub-events were entirely confined to the area associated with oneparticular view, views higher in the hierarchy would still remain asactively involved views.

Event dispatcher module 174 dispatches the event information to an eventrecognizer (e.g., event recognizer 180). In embodiments including activeevent recognizer determination module 173, event dispatcher module 174delivers the event information to an event recognizer determined byactive event recognizer determination module 173. In some embodiments,event dispatcher module 174 stores in an event queue the eventinformation, which is retrieved by a respective event receiver module182.

In some embodiments, operating system 126 includes event sorter 170.Alternatively, application 136-1 includes event sorter 170. In yet otherembodiments, event sorter 170 is a stand-alone module, or a part ofanother module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of eventhandlers 190 and one or more application views 191, each of whichincludes instructions for handling touch events that occur within arespective view of the application's user interface. Each applicationview 191 of the application 136-1 includes one or more event recognizers180. Typically, a respective application view 191 includes a pluralityof event recognizers 180. In other embodiments, one or more of eventrecognizers 180 are part of a separate module, such as a user interfacekit (not shown) or a higher level object from which application 136-1inherits methods and other properties. In some embodiments, a respectiveevent handler 190 includes one or more of: data updater 176, objectupdater 177, GUI updater 178, and/or event data 179 received from eventsorter 170. Event handler 190 optionally uses or calls data updater 176,object updater 177 or GUI updater 178 to update the application internalstate 192. Alternatively, one or more of the application views 191includes one or more respective event handlers 190. Also, in someembodiments, one or more of data updater 176, object updater 177, andGUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g.,event data 179) from event sorter 170, and identifies an event from theevent information. Event recognizer 180 includes event receiver 182 andevent comparator 184. In some embodiments, event recognizer 180 alsoincludes at least a subset of: metadata 183, and event deliveryinstructions 188 (which optionally include sub-event deliveryinstructions).

Event receiver 182 receives event information from event sorter 170. Theevent information includes information about a sub-event, for example, atouch or a touch movement. Depending on the sub-event, the eventinformation also includes additional information, such as location ofthe sub-event. When the sub-event concerns motion of a touch, the eventinformation optionally also includes speed and direction of thesub-event. In some embodiments, events include rotation of the devicefrom one orientation to another (e.g., from a portrait orientation to alandscape orientation, or vice versa), and the event informationincludes corresponding information about the current orientation (alsocalled device attitude) of the device.

Event comparator 184 compares the event information to predefined eventor sub-event definitions and, based on the comparison, determines anevent or sub-event, or determines or updates the state of an event orsub-event. In some embodiments, event comparator 184 includes eventdefinitions 186. Event definitions 186 contain definitions of events(e.g., predefined sequences of sub-events), for example, event 1(187-1), event 2 (187-2), and others. In some embodiments, sub-events inan event 187 include, for example, touch begin, touch end, touchmovement, touch cancellation, and multiple touching. In one example, thedefinition for event 1 (187-1) is a double tap on a displayed object.The double tap, for example, comprises a first touch (touch begin) onthe displayed object for a predetermined phase, a first lift-off (touchend) for a predetermined phase, a second touch (touch begin) on thedisplayed object for a predetermined phase, and a second lift-off (touchend) for a predetermined phase. In another example, the definition forevent 2 (187-2) is a dragging on a displayed object. The dragging, forexample, comprises a touch (or contact) on the displayed object for apredetermined phase, a movement of the touch across touch-sensitivedisplay system 112, and lift-off of the touch (touch end). In someembodiments, the event also includes information for one or moreassociated event handlers 190.

In some embodiments, event definition 187 includes a definition of anevent for a respective user-interface object. In some embodiments, eventcomparator 184 performs a hit test to determine which user-interfaceobject is associated with a sub-event. For example, in an applicationview in which three user-interface objects are displayed ontouch-sensitive display system 112, when a touch is detected ontouch-sensitive display system 112, event comparator 184 performs a hittest to determine which of the three user-interface objects isassociated with the touch (sub-event). If each displayed object isassociated with a respective event handler 190, the event comparatoruses the result of the hit test to determine which event handler 190should be activated. For example, event comparator 184 selects an eventhandler associated with the sub-event and the object triggering the hittest.

In some embodiments, the definition for a respective event 187 alsoincludes delayed actions that delay delivery of the event informationuntil after it has been determined whether the sequence of sub-eventsdoes or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series ofsub-events do not match any of the events in event definitions 186, therespective event recognizer 180 enters an event impossible, eventfailed, or event ended state, after which it disregards subsequentsub-events of the touch-based gesture. In this situation, other eventrecognizers, if any, that remain active for the hit view continue totrack and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata183 with configurable properties, flags, and/or lists that indicate howthe event delivery system should perform sub-event delivery to activelyinvolved event recognizers. In some embodiments, metadata 183 includesconfigurable properties, flags, and/or lists that indicate how eventrecognizers interact, or are enabled to interact, with one another. Insome embodiments, metadata 183 includes configurable properties, flags,and/or lists that indicate whether sub-events are delivered to varyinglevels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates eventhandler 190 associated with an event when one or more particularsub-events of an event are recognized. In some embodiments, a respectiveevent recognizer 180 delivers event information associated with theevent to event handler 190. Activating an event handler 190 is distinctfrom sending (and deferred sending) sub-events to a respective hit view.In some embodiments, event recognizer 180 throws a flag associated withthe recognized event, and event handler 190 associated with the flagcatches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-eventdelivery instructions that deliver event information about a sub-eventwithout activating an event handler. Instead, the sub-event deliveryinstructions deliver event information to event handlers associated withthe series of sub-events or to actively involved views. Event handlersassociated with the series of sub-events or with actively involved viewsreceive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used inapplication 136-1. For example, data updater 176 updates the telephonenumber used in contacts module 137, or stores a video file used in videoplayer module 145. In some embodiments, object updater 177 creates andupdates objects used in application 136-1. For example, object updater177 creates a new user-interface object or updates the position of auser-interface object. GUI updater 178 updates the GUI. For example, GUIupdater 178 prepares display information and sends it to graphics module132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to dataupdater 176, object updater 177, and GUI updater 178. In someembodiments, data updater 176, object updater 177, and GUI updater 178are included in a single module of a respective application 136-1 orapplication view 191. In other embodiments, they are included in two ormore software modules.

It shall be understood that the foregoing discussion regarding eventhandling of user touches on touch-sensitive displays also applies toother forms of user inputs to operate multifunction devices 100 withinput-devices, not all of which are initiated on touch screens. Forexample, mouse movement and mouse button presses, optionally coordinatedwith single or multiple keyboard presses or holds; contact movementssuch as taps, drags, scrolls, etc., on touch-pads; pen stylus inputs;movement of the device; oral instructions; detected eye movements;biometric inputs; and/or any combination thereof are optionally used asinputs corresponding to sub-events which define an event to berecognized.

FIG. 2 illustrates a portable multifunction device 100 having a touchscreen (e.g., touch-sensitive display system 112, FIG. 1A) in accordancewith some embodiments. The touch screen optionally displays one or moregraphics within user interface (UI) 200. In this embodiment, as well asothers described below, a user is enabled to select one or more of thegraphics by making a gesture on the graphics, for example, with one ormore fingers 202 (not drawn to scale in the figure) or one or morestyluses 203 (not drawn to scale in the figure). In some embodiments,selection of one or more graphics occurs when the user breaks contactwith the one or more graphics. In some embodiments, the gestureoptionally includes one or more taps, one or more swipes (from left toright, right to left, upward and/or downward) and/or a rolling of afinger (from right to left, left to right, upward and/or downward) thathas made contact with device 100. In some implementations orcircumstances, inadvertent contact with a graphic does not select thegraphic. For example, a swipe gesture that sweeps over an applicationicon optionally does not select the corresponding application when thegesture corresponding to selection is a tap.

Device 100 optionally also includes one or more physical buttons, suchas “home” or menu button 204. As described previously, menu button 204is, optionally, used to navigate to any application 136 in a set ofapplications that are, optionally executed on device 100. Alternatively,in some embodiments, the menu button is implemented as a soft key in aGUI displayed on the touch-screen display.

In some embodiments, device 100 includes the touch-screen display, menubutton 204, push button 206 for powering the device on/off and lockingthe device, volume adjustment button(s) 208, Subscriber Identity Module(SIM) card slot 210, head set jack 212, and docking/charging externalport 124. Push button 206 is, optionally, used to turn the power on/offon the device by depressing the button and holding the button in thedepressed state for a predefined time interval; to lock the device bydepressing the button and releasing the button before the predefinedtime interval has elapsed; and/or to unlock the device or initiate anunlock process. In some embodiments, device 100 also accepts verbalinput for activation or deactivation of some functions throughmicrophone 113. Device 100 also, optionally, includes one or morecontact intensity sensors 165 for detecting intensity of contacts ontouch-sensitive display system 112 and/or one or more tactile outputgenerators 167 for generating tactile outputs for a user of device 100.

FIG. 3 is a block diagram of an example of a multifunction device with adisplay and a touch-sensitive surface in accordance with someembodiments. Device 300 need not be portable. In some embodiments,device 300 is a laptop computer, a desktop computer, a tablet computer,a multimedia player device, a navigation device, an educational device(such as a child's learning toy), a gaming system, or a control device(e.g., a home or industrial controller). Device 300 typically includesone or more processing units (CPU's) 310, one or more network or othercommunications interfaces 360, memory 370, and one or more communicationbuses 320 for interconnecting these components. Communication buses 320optionally include circuitry (sometimes called a chipset) thatinterconnects and controls communications between system components.Device 300 includes input/output (I/O) interface 330 comprising display340, which is typically a touch-screen display. I/O interface 330 alsooptionally includes a keyboard and/or mouse (or other pointing device)350 and touchpad 355, tactile output generator 357 for generatingtactile outputs on device 300 (e.g., similar to tactile outputgenerator(s) 167 described above with reference to FIG. 1A), sensors 359(e.g., optical, acceleration, proximity, touch-sensitive, and/or contactintensity sensors similar to contact intensity sensor(s) 165 describedabove with reference to FIG. 1A). Memory 370 includes high-speed randomaccess memory, such as DRAM, SRAM, DDR RAM or other random access solidstate memory devices; and optionally includes non-volatile memory, suchas one or more magnetic disk storage devices, optical disk storagedevices, flash memory devices, or other non-volatile solid state storagedevices. Memory 370 optionally includes one or more storage devicesremotely located from CPU(s) 310. In some embodiments, memory 370 storesprograms, modules, and data structures analogous to the programs,modules, and data structures stored in memory 102 of portablemultifunction device 100 (FIG. 1A), or a subset thereof. Furthermore,memory 370 optionally stores additional programs, modules, and datastructures not present in memory 102 of portable multifunction device100. For example, memory 370 of device 300 optionally stores drawingmodule 380, presentation module 382, word processing module 384, websitecreation module 386, disk authoring module 388, and/or spreadsheetmodule 390, while memory 102 of portable multifunction device 100 (FIG.1A) optionally does not store these modules.

Each of the above-identified elements in FIG. 3 are, optionally, storedin one or more of the previously mentioned memory devices. Each of theabove identified modules corresponds to a set of instructions forperforming a function described above. The above identified modules orprograms (i.e., sets of instructions) need not be implemented asseparate software programs, procedures or modules, and thus varioussubsets of these modules are, optionally, combined or otherwisere-arranged in various embodiments. In some embodiments, memory 370optionally stores a subset of the modules and data structures identifiedabove. Furthermore, memory 370 optionally stores additional modules anddata structures not described above.

Attention is now directed towards embodiments of user interfaces (“UI”)that are, optionally, implemented on portable multifunction device 100.

FIG. 4A illustrates an example user interface for a menu of applicationson portable multifunction device 100 in accordance with someembodiments. Similar user interfaces are, optionally, implemented ondevice 300. In some embodiments, user interface 400 includes thefollowing elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),        such as cellular and Wi-Fi signals;    -   Time 404;    -   Bluetooth indicator 405;    -   Battery status indicator 406;    -   Tray 408 with icons for frequently used applications, such as:        -   Icon 416 for telephone module 138, labeled “Phone,” which            optionally includes an indicator 414 of the number of missed            calls or voicemail messages;        -   Icon 418 for e-mail client module 140, labeled “Mail,” which            optionally includes an indicator 410 of the number of unread            e-mails;        -   Icon 420 for browser module 147, labeled “Browser;” and        -   Icon 422 for video and music player module 152, also            referred to as iPod (trademark of Apple Inc.) module 152,            labeled “iPod;” and    -   Icons for other applications, such as:        -   Icon 424 for IM module 141, labeled “Messages;”        -   Icon 426 for calendar module 148, labeled “Calendar;”        -   Icon 428 for image management module 144, labeled “Photos;”        -   Icon 430 for camera module 143, labeled “Camera;”        -   Icon 432 for online video module 155, labeled “Online            Video;”        -   Icon 434 for stocks widget 149-2, labeled “Stocks;”        -   Icon 436 for map module 154, labeled “Map;”        -   Icon 438 for weather widget 149-1, labeled “Weather;”        -   Icon 440 for alarm clock widget 149-4, labeled “Clock;”        -   Icon 442 for news module 142, labeled “News;”        -   Icon 444 for notes module 153, labeled “Notes;” and        -   Icon 446 for a settings application or module, which            provides access to settings for device 100 and its various            applications 136.

It should be noted that the icon labels illustrated in FIG. 4A aremerely examples. For example, in some embodiments, icon 422 for videoand music player module 152 is labeled “Music” or “Music Player.” Otherlabels are, optionally, used for various application icons. In someembodiments, a label for a respective application icon includes a nameof an application corresponding to the respective application icon. Insome embodiments, a label for a particular application icon is distinctfrom a name of an application corresponding to the particularapplication icon.

FIG. 4B illustrates an example user interface on a device (e.g., device300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tablet ortouchpad 355, FIG. 3) that is separate from the display 450. Device 300also, optionally, includes one or more contact intensity sensors (e.g.,one or more of sensors 357) for detecting intensity of contacts ontouch-sensitive surface 451 and/or one or more tactile output generators359 for generating tactile outputs for a user of device 300. Althoughmany of the examples that follow will be given with reference to inputson touch screen display 112 (where the touch-sensitive surface and thedisplay are combined), in some embodiments, the device detects inputs ona touch-sensitive surface that is separate from the display, as shown inFIG. 4B. In some embodiments, the touch-sensitive surface (e.g., 451 inFIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) that corresponds to aprimary axis (e.g., 453 in FIG. 4B) on the display (e.g., 450). Inaccordance with these embodiments, the device detects contacts (e.g.,460 and 462 in FIG. 4B) with the touch-sensitive surface 451 atlocations that correspond to respective locations on the display (e.g.,in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470). In thisway, user inputs (e.g., contacts 460 and 462, and movements thereof)detected by the device on the touch-sensitive surface (e.g., 451 in FIG.4B) are used by the device to manipulate the user interface on thedisplay (e.g., 450 in FIG. 4B) of the multifunction device when thetouch-sensitive surface is separate from the display. It should beunderstood that similar methods are, optionally, used for other userinterfaces described herein.

Additionally, while the following examples are given primarily withreference to finger inputs (e.g., finger contacts, finger tap gestures,finger swipe gestures, etc.), it should be understood that, in someembodiments, one or more of the finger inputs are replaced with inputfrom another input device (e.g., a mouse based input or a stylus input).For example, a swipe gesture is, optionally, replaced with a mouse click(e.g., instead of a contact) followed by movement of the cursor alongthe path of the swipe (e.g., instead of movement of the contact). Asanother example, a tap gesture is, optionally, replaced with a mouseclick while the cursor is located over the location of the tap gesture(e.g., instead of detection of the contact followed by ceasing to detectthe contact). Similarly, when multiple user inputs are simultaneouslydetected, it should be understood that multiple computer mice are,optionally, used simultaneously, or a mouse and finger contacts are,optionally, used simultaneously.

As used herein, the term “focus selector” refers to an input elementthat indicates a current part of a user interface with which a user isinteracting. In some implementations that include a cursor or otherlocation marker, the cursor acts as a “focus selector,” so that when aninput (e.g., a press input) is detected on a touch-sensitive surface(e.g., touchpad 355 in FIG. 3 or touch-sensitive surface 451 in FIG. 4B)while the cursor is over a particular user interface element (e.g., abutton, window, slider or other user interface element), the particularuser interface element is adjusted in accordance with the detectedinput. In some implementations that include a touch-screen display(e.g., touch-sensitive display system 112 in FIG. 1A or the touch screenin FIG. 4A) that enables direct interaction with user interface elementson the touch-screen display, a detected contact on the touch-screen actsas a “focus selector,” so that when an input (e.g., a press input by thecontact) is detected on the touch-screen display at a location of aparticular user interface element (e.g., a button, window, slider orother user interface element), the particular user interface element isadjusted in accordance with the detected input. In some implementations,focus is moved from one region of a user interface to another region ofthe user interface without corresponding movement of a cursor ormovement of a contact on a touch-screen display (e.g., by using a tabkey or arrow keys to move focus from one button to another button); inthese implementations, the focus selector moves in accordance withmovement of focus between different regions of the user interface.Without regard to the specific form taken by the focus selector, thefocus selector is generally the user interface element (or contact on atouch-screen display) that is controlled by the user so as tocommunicate the user's intended interaction with the user interface(e.g., by indicating, to the device, the element of the user interfacewith which the user is intending to interact). For example, the locationof a focus selector (e.g., a cursor, a contact, or a selection box) overa respective button while a press input is detected on thetouch-sensitive surface (e.g., a touchpad or touch screen) will indicatethat the user is intending to activate the respective button (as opposedto other user interface elements shown on a display of the device).

As used in the specification and claims, the term “intensity” of acontact on a touch-sensitive surface refers to the force or pressure(force per unit area) of a contact (e.g., a finger contact or a styluscontact) on the touch-sensitive surface, or to a substitute (proxy) forthe force or pressure of a contact on the touch-sensitive surface. Theintensity of a contact has a range of values that includes at least fourdistinct values and more typically includes hundreds of distinct values(e.g., at least 256). Intensity of a contact is, optionally, determined(or measured) using various approaches and various sensors orcombinations of sensors. For example, one or more force sensorsunderneath or adjacent to the touch-sensitive surface are, optionally,used to measure force at various points on the touch-sensitive surface.In some implementations, force measurements from multiple force sensorsare combined (e.g., a weighted average or a sum) to determine anestimated force of a contact. Similarly, a pressure-sensitive tip of astylus is, optionally, used to determine a pressure of the stylus on thetouch-sensitive surface. Alternatively, the size of the contact areadetected on the touch-sensitive surface and/or changes thereto, thecapacitance of the touch-sensitive surface proximate to the contactand/or changes thereto, and/or the resistance of the touch-sensitivesurface proximate to the contact and/or changes thereto are, optionally,used as a substitute for the force or pressure of the contact on thetouch-sensitive surface. In some implementations, the substitutemeasurements for contact force or pressure are used directly todetermine whether an intensity threshold has been exceeded (e.g., theintensity threshold is described in units corresponding to thesubstitute measurements). In some implementations, the substitutemeasurements for contact force or pressure are converted to an estimatedforce or pressure and the estimated force or pressure is used todetermine whether an intensity threshold has been exceeded (e.g., theintensity threshold is a pressure threshold measured in units ofpressure). Using the intensity of a contact as an attribute of a userinput allows for user access to additional device functionality that mayotherwise not be readily accessible by the user on a reduced-size devicewith limited real estate for displaying affordances (e.g., on atouch-sensitive display) and/or receiving user input (e.g., via atouch-sensitive display, a touch-sensitive surface, or aphysical/mechanical control such as a knob or a button).

In some embodiments, contact/motion module 130 uses a set of one or moreintensity thresholds to determine whether an operation has beenperformed by a user (e.g., to determine whether a user has “clicked” onan icon). In some embodiments, at least a subset of the intensitythresholds are determined in accordance with software parameters (e.g.,the intensity thresholds are not determined by the activation thresholdsof particular physical actuators and can be adjusted without changingthe physical hardware of device 100). For example, a mouse “click”threshold of a trackpad or touch-screen display can be set to any of alarge range of predefined thresholds values without changing thetrackpad or touch-screen display hardware. Additionally, in someimplementations a user of the device is provided with software settingsfor adjusting one or more of the set of intensity thresholds (e.g., byadjusting individual intensity thresholds and/or by adjusting aplurality of intensity thresholds at once with a system-level click“intensity” parameter).

As used in the specification and claims, the term “characteristicintensity” of a contact refers to a characteristic of the contact basedon one or more intensities of the contact. In some embodiments, thecharacteristic intensity is based on multiple intensity samples. Thecharacteristic intensity is, optionally, based on a predefined number ofintensity samples, or a set of intensity samples collected during apredetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10seconds) relative to a predefined event (e.g., after detecting thecontact, prior to detecting liftoff of the contact, before or afterdetecting a start of movement of the contact, prior to detecting an endof the contact, before or after detecting an increase in intensity ofthe contact, and/or before or after detecting a decrease in intensity ofthe contact). A characteristic intensity of a contact is, optionallybased on one or more of: a maximum value of the intensities of thecontact, a mean value of the intensities of the contact, an averagevalue of the intensities of the contact, a top 10 percentile value ofthe intensities of the contact, a value at the half maximum of theintensities of the contact, a value at the 90 percent maximum of theintensities of the contact, or the like. In some embodiments, theduration of the contact is used in determining the characteristicintensity (e.g., when the characteristic intensity is an average of theintensity of the contact over time). In some embodiments, thecharacteristic intensity is compared to a set of one or more intensitythresholds to determine whether an operation has been performed by auser. For example, the set of one or more intensity thresholds mayinclude a first intensity threshold and a second intensity threshold. Inthis example, a contact with a characteristic intensity that does notexceed the first threshold results in a first operation, a contact witha characteristic intensity that exceeds the first intensity thresholdand does not exceed the second intensity threshold results in a secondoperation, and a contact with a characteristic intensity that exceedsthe second intensity threshold results in a third operation. In someembodiments, a comparison between the characteristic intensity and oneor more intensity thresholds is used to determine whether or not toperform one or more operations (e.g., whether to perform a respectiveoption or forgo performing the respective operation) rather than beingused to determine whether to perform a first operation or a secondoperation.

In some embodiments, a portion of a gesture is identified for purposesof determining a characteristic intensity. For example, atouch-sensitive surface may receive a continuous swipe contacttransitioning from a start location and reaching an end location (e.g.,a drag gesture), at which point the intensity of the contact increases.In this example, the characteristic intensity of the contact at the endlocation may be based on only a portion of the continuous swipe contact,and not the entire swipe contact (e.g., only the portion of the swipecontact at the end location). In some embodiments, a smoothing algorithmmay be applied to the intensities of the swipe contact prior todetermining the characteristic intensity of the contact. For example,the smoothing algorithm optionally includes one or more of: anunweighted sliding-average smoothing algorithm, a triangular smoothingalgorithm, a median filter smoothing algorithm, and/or an exponentialsmoothing algorithm. In some circumstances, these smoothing algorithmseliminate narrow spikes or dips in the intensities of the swipe contactfor purposes of determining a characteristic intensity.

The user interface figures (e.g., FIGS. 5A-5OO) described hereinoptionally include various intensity diagrams that show the currentintensity of the contact on the touch-sensitive surface relative to oneor more intensity thresholds (e.g., a contact detection intensitythreshold IT₀, a light press intensity threshold IT_(L), a deep pressintensity threshold ITS (e.g., that is at least initially higher thanI_(L)), and/or one or more other intensity thresholds (e.g., anintensity threshold I_(H) that is lower than I_(L)). This intensitydiagram is typically not part of the displayed user interface, but isprovided to aid in the interpretation of the figures. In someembodiments, the light press intensity threshold corresponds to anintensity at which the device will perform operations typicallyassociated with clicking a button of a physical mouse or a trackpad. Insome embodiments, the deep press intensity threshold corresponds to anintensity at which the device will perform operations that are differentfrom operations typically associated with clicking a button of aphysical mouse or a trackpad. In some embodiments, when a contact isdetected with a characteristic intensity below the light press intensitythreshold (e.g., and above a nominal contact-detection intensitythreshold IT₀ below which the contact is no longer detected), the devicewill move a focus selector in accordance with movement of the contact onthe touch-sensitive surface without performing an operation associatedwith the light press intensity threshold or the deep press intensitythreshold. Generally, unless otherwise stated, these intensitythresholds are consistent between different sets of user interfacefigures.

In some embodiments, the response of the device to inputs detected bythe device depends on criteria based on the contact intensity during theinput. For example, for some “light press” inputs, the intensity of acontact exceeding a first intensity threshold during the input triggersa first response. In some embodiments, the response of the device toinputs detected by the device depends on criteria that include both thecontact intensity during the input and time-based criteria. For example,for some “deep press” inputs, the intensity of a contact exceeding asecond intensity threshold during the input, greater than the firstintensity threshold for a light press, triggers a second response onlyif a delay time has elapsed between meeting the first intensitythreshold and meeting the second intensity threshold. This delay time istypically less than 200 ms in duration (e.g., 40, 100, or 120 ms,depending on the magnitude of the second intensity threshold, with thedelay time increasing as the second intensity threshold increases). Thisdelay time helps to avoid accidental deep press inputs. As anotherexample, for some “deep press” inputs, there is a reduced-sensitivitytime period that occurs after the time at which the first intensitythreshold is met. During the reduced-sensitivity time period, the secondintensity threshold is increased. This temporary increase in the secondintensity threshold also helps to avoid accidental deep press inputs.For other deep press inputs, the response to detection of a deep pressinput does not depend on time-based criteria.

In some embodiments, one or more of the input intensity thresholdsand/or the corresponding outputs vary based on one or more factors, suchas user settings, contact motion, input timing, application running,rate at which the intensity is applied, number of concurrent inputs,user history, environmental factors (e.g., ambient noise), focusselector position, and the like. Example factors are described in U.S.patent application Ser. Nos. 14/399,606 and 14/624,296, which areincorporated by reference herein in their entireties.

For example, FIG. 4C illustrates a dynamic intensity threshold 480 thatchanges over time based in part on the intensity of touch input 476 overtime. Dynamic intensity threshold 480 is a sum of two components, firstcomponent 474 that decays over time after a predefined delay time p1from when touch input 476 is initially detected, and second component478 that trails the intensity of touch input 476 over time. The initialhigh intensity threshold of first component 474 reduces accidentaltriggering of a “deep press” response, while still allowing an immediate“deep press” response if touch input 476 provides sufficient intensity.Second component 478 reduces unintentional triggering of a “deep press”response by gradual intensity fluctuations of in a touch input. In someembodiments, when touch input 476 satisfies dynamic intensity threshold480 (e.g., at point 481 in FIG. 4C), the “deep press” response istriggered.

FIG. 4D illustrates another dynamic intensity threshold 486 (e.g.,intensity threshold ID). FIG. 4D also illustrates two other intensitythresholds: a first intensity threshold I_(H) and a second intensitythreshold I_(L). In FIG. 4D, although touch input 484 satisfies thefirst intensity threshold I_(H) and the second intensity threshold I_(L)prior to time p2, no response is provided until delay time p2 haselapsed at time 482. Also in FIG. 4D, dynamic intensity threshold 486decays over time, with the decay starting at time 488 after a predefineddelay time p1 has elapsed from time 482 (when the response associatedwith the second intensity threshold I_(L) was triggered). This type ofdynamic intensity threshold reduces accidental triggering of a responseassociated with the dynamic intensity threshold ID immediately after, orconcurrently with, triggering a response associated with a lowerintensity threshold, such as the first intensity threshold I_(H) or thesecond intensity threshold I_(L).

FIG. 4E illustrate yet another dynamic intensity threshold 492 (e.g.,intensity threshold ID). In FIG. 4E, a response associated with theintensity threshold I_(L) is triggered after the delay time p2 haselapsed from when touch input 490 is initially detected. Concurrently,dynamic intensity threshold 492 decays after the predefined delay timep1 has elapsed from when touch input 490 is initially detected. So adecrease in intensity of touch input 490 after triggering the responseassociated with the intensity threshold I_(L), followed by an increasein the intensity of touch input 490, without releasing touch input 490,can trigger a response associated with the intensity threshold ID (e.g.,at time 494) even when the intensity of touch input 490 is below anotherintensity threshold, for example, the intensity threshold I_(L).

An increase of characteristic intensity of the contact from an intensitybelow the light press intensity threshold IT_(L) to an intensity betweenthe light press intensity threshold IT_(L) and the deep press intensitythreshold ITS is sometimes referred to as a “light press” input. Anincrease of characteristic intensity of the contact from an intensitybelow the deep press intensity threshold ITS to an intensity above thedeep press intensity threshold ITS is sometimes referred to as a “deeppress” input. An increase of characteristic intensity of the contactfrom an intensity below the contact-detection intensity threshold IT₀ toan intensity between the contact-detection intensity threshold IT₀ andthe light press intensity threshold IT_(L) is sometimes referred to asdetecting the contact on the touch-surface. A decrease of characteristicintensity of the contact from an intensity above the contact-detectionintensity threshold IT₀ to an intensity below the contact-detectionintensity threshold IT₀ is sometimes referred to as detecting liftoff ofthe contact from the touch-surface. In some embodiments IT₀ is zero. Insome embodiments, IT₀ is greater than zero. In some illustrations ashaded circle or oval is used to represent intensity of a contact on thetouch-sensitive surface. In some illustrations, a circle or oval withoutshading is used represent a respective contact on the touch-sensitivesurface without specifying the intensity of the respective contact.

In some embodiments, described herein, one or more operations areperformed in response to detecting a gesture that includes a respectivepress input or in response to detecting the respective press inputperformed with a respective contact (or a plurality of contacts), wherethe respective press input is detected based at least in part ondetecting an increase in intensity of the contact (or plurality ofcontacts) above a press-input intensity threshold. In some embodiments,the respective operation is performed in response to detecting theincrease in intensity of the respective contact above the press-inputintensity threshold (e.g., the respective operation is performed on a“down stroke” of the respective press input). In some embodiments, thepress input includes an increase in intensity of the respective contactabove the press-input intensity threshold and a subsequent decrease inintensity of the contact below the press-input intensity threshold, andthe respective operation is performed in response to detecting thesubsequent decrease in intensity of the respective contact below thepress-input threshold (e.g., the respective operation is performed on an“up stroke” of the respective press input).

In some embodiments, the device employs intensity hysteresis to avoidaccidental inputs sometimes termed “jitter,” where the device defines orselects a hysteresis intensity threshold with a predefined relationshipto the press-input intensity threshold (e.g., the hysteresis intensitythreshold is X intensity units lower than the press-input intensitythreshold or the hysteresis intensity threshold is 75%, 90%, or somereasonable proportion of the press-input intensity threshold). Thus, insome embodiments, the press input includes an increase in intensity ofthe respective contact above the press-input intensity threshold and asubsequent decrease in intensity of the contact below the hysteresisintensity threshold that corresponds to the press-input intensitythreshold, and the respective operation is performed in response todetecting the subsequent decrease in intensity of the respective contactbelow the hysteresis intensity threshold (e.g., the respective operationis performed on an “up stroke” of the respective press input).Similarly, in some embodiments, the press input is detected only whenthe device detects an increase in intensity of the contact from anintensity at or below the hysteresis intensity threshold to an intensityat or above the press-input intensity threshold and, optionally, asubsequent decrease in intensity of the contact to an intensity at orbelow the hysteresis intensity, and the respective operation isperformed in response to detecting the press input (e.g., the increasein intensity of the contact or the decrease in intensity of the contact,depending on the circumstances).

For ease of explanation, the description of operations performed inresponse to a press input associated with a press-input intensitythreshold or in response to a gesture including the press input are,optionally, triggered in response to detecting: an increase in intensityof a contact above the press-input intensity threshold, an increase inintensity of a contact from an intensity below the hysteresis intensitythreshold to an intensity above the press-input intensity threshold, adecrease in intensity of the contact below the press-input intensitythreshold, or a decrease in intensity of the contact below thehysteresis intensity threshold corresponding to the press-inputintensity threshold. Additionally, in examples where an operation isdescribed as being performed in response to detecting a decrease inintensity of a contact below the press-input intensity threshold, theoperation is, optionally, performed in response to detecting a decreasein intensity of the contact below a hysteresis intensity thresholdcorresponding to, and lower than, the press-input intensity threshold.As described above, in some embodiments, the triggering of theseresponses also depends on time-based criteria being met (e.g., a delaytime has elapsed between a first intensity threshold being met and asecond intensity threshold being met).

USER INTERFACES AND ASSOCIATED PROCESSES

Attention is now directed towards embodiments of user interfaces (“UI”)and associated processes that may be implemented using an electronicdevice that communicates with and/or includes a display and atouch-sensitive surface, such as a computing device (e.g., device 100 ofFIG. 4A). In some embodiments, the computing device includes one or moresensors to detect intensities of contacts with the touch-sensitivesurface. In some embodiments, the computing device includes the display.In some embodiments, the computing device includes an audio system. Insome embodiments, the computing device includes neither the display northe audio system. In some embodiments, the display includes the audiosystem (e.g., the display and the audio system are components of atelevision). In some embodiments, certain components of the audio systemand the display are separate (e.g., the display is a component of atelevision and the audio system includes a sound bar that is separatefrom the television). In some embodiments, the computing device is incommunication with a separate remote control through which it receivesuser inputs (e.g., the remote control includes a touch-sensitive surfaceor a touch screen through which the user interacts with the computingdevice). In some embodiments, the remote control includes a motionsensor (e.g., an accelerometer and/or a gyroscope) to detect a motion ofthe remote control (e.g., a user picking up the remote control).

For convenience of explanation, some of the embodiments will bediscussed with reference to operations performed on a device with atouch-sensitive display system 112. In such embodiments, the focusselector is, optionally: a respective finger or stylus contact, arepresentative point corresponding to a finger or stylus contact (e.g.,a centroid of a respective contact or a point associated with arespective contact), or a centroid of two or more contacts detected onthe touch-sensitive display system 112. However, analogous operationsare, optionally, performed on a device with a display 450 and a separatetouch-sensitive surface 451 in response to detecting the contacts on thetouch-sensitive surface 451 while displaying the user interfaces shownin the figures on the display 450, along with a focus selector.

FIGS. 5A-5OO illustrate example user interfaces for media playbackcontrol using intensity-based input, in accordance with someembodiments. The user interfaces in these figures are used to illustratethe processes described below, including the processes in FIGS. 6A-6Cand 8A-8C.

FIG. 5A illustrates an example user interface on the display 100. Theuser interface includes a list of different music tracks 501 a-501 c bydifferent artists. Each music track-501 c is associated with arespective play button 502 a-502 c that, when selected, results in thedisplay of a media player user interface for presenting the associatedmusic track-501 c. Each music track-501 c is also associated with arespective content label 504 a-504 c that identifies the band name andsong name for each music track 501 a-501 c.

FIGS. 5B-5D illustrates example user interfaces, displayed subsequent tothe user interface of FIG. 5A, to initiate display of, and use, a firstmedia player user interface. In FIG. 5B, the device 100 detects a tapgesture 509-1. In response, the device 100 determines whether to displaythe first media player user interface based on whether the tap gesture509-1 remains below a light press intensity threshold IT_(L). Becausethe intensity of the tap gesture 509-1 remains below a light pressintensity threshold IT_(L), as illustrated in the intensity of contactchart 530, the device 100 displays the first media player user interfaceshown in FIG. 5C. The first media player user interface includes a musictrack label 514 identifying music track selected by the user via the tapgesture 509-1 shown in FIG. 5B. The first media player user interfacealso includes a rewind icon 512 a, player icon 512 b and fast-forwardicon 512 c which causes the device to rewind, play or fast-forward themusic track based on activation of the icons 512 a-512 c, respectively.For example, in FIG. 5C, the device 100 detects a tap gesture 510-1 onplayer icon 512 b. Subsequently, as shown in FIG. 5D, the device 100presents music track via speaker 111 (as illustrated by sound waves 526emanating from the device 100) in response to activation of player icon512 b.

FIGS. 5E-5J illustrates example user interfaces, displayed subsequent tothe example user interface of FIG. 5A, to initiate display of, and use,a second media player user interface. In FIG. 5E, the device 100 detectsa tap gesture 509-2. In response, the device 100 determines whether todisplay the second media player user interface based on whether the tapgesture 509-2 exceeds a light press intensity threshold IT_(L). Becausethe intensity of the tap gesture 509-2 exceeds the light press intensitythreshold IT_(L), the device 100 displays the second media player userinterface shown in FIG. 5F. In FIG. 5F, the second media player userinterface includes a music track label 514 identifying the music trackselected by the user via the tap gesture 510-2 shown in FIG. 5E. Thesecond media player user interface also includes a rewind zone 518 a,play zone 518 b and fast-forward zone 518 c that are typically notvisible to the user. Each of the zones 518 a-518 c includesfunctionality that corresponds to the functionality of icons 512 a-512 cshown in FIG. 5C. For example, device 100 presents the music track viaspeaker 111 in response to activation of player zone 518 b (e.g., suchas by a tap gesture 510-2 with an intensity that exceeds a light pressintensity threshold IT_(L) as shown in FIG. 5G-5H and illustrated assound waves 526 emanating from device 100 as shown in FIG. 5H), rewindsthe music track in response to activation of the rewind zone 518 a andfast forwards the music track in response to activation of thefast-forward zone 518 c. In some embodiments, as shown in FIGS. 5I-5J,the device detects a tap gesture 510-3. In response, the device 100determines whether to continue playing, or pause, the music track basedon whether the tap gesture 510-3 exceeds a light press intensitythreshold IT_(L). Because the intensity of the tap gesture 510-3 doesnot exceed the light press intensity threshold IT_(L), the device 100continues to play the selected music track, as shown in FIG. 5J.

FIGS. 5K-5L illustrates alternative example user interfaces, displayedsubsequent to the example user interface of FIG. 5A, to initiate displayof the first media player user interface. In FIG. 5K, the device 100detects a swipe gesture 511-2 moving from an initial position 511-1 at aperimeter of the display 400. In response, the device 100 determineswhether to display a first media player user interface based on whetherthe swipe gesture 511-2 is moving from the perimeter of the display 400and a characteristic intensity of the swipe gesture 511-2 remains belowa light press intensity threshold IT_(L). In this example, because theswipe gesture 511-2 is moving from the perimeter of the display 400 anda characteristic intensity of the swipe gesture 511-2 remains below thelight press intensity threshold IT_(L), the device 100 displays thefirst media player user interface, as shown in FIG. 5L.

FIGS. 5M-5N illustrates alternative example user interfaces, displayedsubsequent to the example user interface of FIG. 5A, to initiate displayof the second media player user interface. In FIG. 5M, the device 100detects a swipe gesture 511-4 moving from an initial position 511-3 at aperimeter of the display 400. In response, the device 100 determineswhether to display a second media player user interface based on whetherthe swipe gesture 511-4 is moving from the perimeter of the display 400and a characteristic intensity of the swipe gesture 511-4 exceeds alight press intensity threshold IT_(L). In this example, because theswipe gesture 511-4 is moving from the perimeter of the display 400 anda characteristic intensity of the swipe gesture 511-4 exceeds the lightpress intensity threshold IT_(L), the device 100 displays the secondmedia player user interface, as shown in FIG. 5N.

FIGS. 5O-5P illustrate example user interfaces for toggling between thefirst media player user interface and the second media player userinterface. FIG. 5O shows the device 100 displaying the first mediaplayer user interface. In this example, the device 100 detects a swipegesture 530-2 moving from an initial position 530-1. In response, thedevice 100 determines whether to display the second media player userinterface based on whether the swipe gesture 530-2 is moving. In thisexample, because the swipe gesture 530-2 is moving, the device 100toggles to display of the second media player user interface, as shownin FIG. 5P.

FIG. 5Q-5R illustrate alternative example user interfaces for togglingbetween the first media player user interface and the second mediaplayer user interface. FIG. 5Q shows the device 100 displaying the firstmedia player user interface. In this example, the device 100 detects atap gesture 531. In response, the device 100 determines whether todisplay a second media player user interface based on whether the tapgesture 531 exceeds a light press intensity threshold IT_(L). In thisexample, because the tap gesture 531 exceeds the light press intensitythreshold IT_(L), the device 100 toggles to display of the second mediaplayer user interface as shown in FIG. 5R.

FIGS. 5S-5T illustrate example user interfaces showing an examplefeedback response by the device 100 while displaying the first mediaplayer user interface. In FIG. 5S, the device 100 displays the firstmedia player user interface playing music track Song No. 1 by Band No.1, illustrated by music track label 514. The device detects a tapgesture 532 of fast-forward icon 512 c, as shown in FIG. 5S. Inresponse, as shown in FIG. 5T, the device 100 enlarges the fast-forwardicon 512 c as compared to rewind icon 512 a and play icon 512 b. Inaddition, the device 100 transitions to music track Song No. 2 by BandNo. 2, illustrated by music track label 515.

FIGS. 5U-5V illustrate example user interfaces showing an examplefeedback response by the device 100 while displaying the second mediaplayer user interface. In FIG. 5U, the device 100 displays the secondmedia player user interface playing music track Song No. 1 by Band No.1, illustrated by music track label 514. The device 100 detects a tapgesture 534, at fast-forward zone 518 c, with a characteristic intensitythat exceeds a light press intensity threshold IT_(L). In response, asshown in FIG. 5V, the device 100 vibrates, as illustrated by hapticfeedback lines 520. In addition, the device 100 transitions to musictrack Song No. 2 by Band No. 2, illustrated by music track label 515.Alternatively or in addition to providing haptic feedback 520, as shownin FIG. 5W, the device 100 displays a solid line circle 535 or othergraphic at the position of the user input 534, shown in FIG. 5U, inresponse to detecting the tap gesture 534 at fast-forward zone 518 cwith a characteristic intensity that exceeds a light press intensitythreshold IT_(L). In addition, in either example, the device 100transitions to music track Song No. 2 by Band No. 2, illustrated bymusic track label 515.

FIGS. 5X-5CC illustrate example user interfaces showing selectiveforward scrubbing or skip to a next music track functionality by thedevice 100 while displaying the second media player user interface. InFIG. 5X, the device 100 displays the second media player user interfaceincluding a music track label 514 corresponding to music track Song No.1 by Band No. 1. In this example, the device 100 detects a gesture 536-1at the fast-forward zone 518 c (e.g., a tap or press gesture). If thegesture 536-1 exceeds a light press intensity threshold IT_(L) andremains below a deep press intensity threshold IT_(D), the device 100,as shown in FIG. 5Y, skips to the next music track Song No. 2 by BandNo. 2 and the second media player user interface displays music tracklabel 515. However, if the device 100 detects a gesture 536-2 thatexceeds the deep press intensity threshold IT_(D), as shown in FIG. 5Z,the device 100 scrubs the music track Song No. 1 by Band No. 1. Thescrubbing functionality is illustrated by scrubber bar graphic 524-1shown in FIGS. 5AA-5CC. Initially, as shown in FIG. 5AA, the scrubberbar graphic 524-1 illustrates that the initial presentation position of0:35 of the music track. As the gesture 536-2 continues to exceed thedeep press intensity threshold IT_(D), the device 100 continues to scrubthe music track, as shown sequentially in FIG. 5BB, where the subsequentpresentation position of the music track is 0:45, rather than 0:36. Insome embodiments, the scrubbing speed increases as the contact ingesture 536-3 moves laterally across the screen (e.g., in a rightwardswipe), as shown in FIG. 5CC, where the contact in rightward swipegesture 536-3 moves from initial position 537-1 to position 537-2. InFIG. 5CC, the subsequent presentation position of the music track is1:05, rather than 0:55 (e.g., the presentation position of the musictrack as a result of continuation of tap gesture 536-2 rather thanrightward swipe gesture 536-3).

FIGS. 5DD-5GG illustrate example user interfaces showing togglingbetween playing or pausing a music track while displaying the secondmedia player user interface. In FIG. 5DD, the device 100 displays thesecond media player user interface including a music track label 514corresponding to music track Song No. 1 by Band No. 1. In this example,the device 100 is presenting the music track to the user via speaker 111and illustrated by sound waves 526 emanating from the device 100. Thedevice 100 detects a tap gesture 538-1 at player zone 518 b. If the tapgesture 538-1 exceeds a light press threshold IT_(L) and remains below adeep press intensity threshold IT_(D), the device 100 toggles to pausingpresentation of the music track, as shown in FIG. 5EE. Subsequently, ifthe device 100 detects a tap gesture 538-2 that exceeds a light pressthreshold IT_(L) and remains below a deep press intensity thresholdIT_(D), as shown in FIG. 5FF the device 100 toggles to playing the musictrack Song No. 1 by Band No. 1, as shown in FIG. 5GG.

Additional scrubbing functionality is illustrated by scrubber bargraphic 524-2 in FIGS. 5HH-5JJ. In FIG. 5HH, the device 100 ispresenting the music track to the user via speaker 111 and illustratedby sound waves 526 emanating from the device 100. In response to a tapgesture 538-3 that exceeds a deep press intensity threshold IT_(D), thedevice 100 scrubs the music track as illustrated by the scrubber bargraphic 524-2. As the tap gesture 538-3 continues to exceed the deeppress intensity threshold IT_(D), the device 100 continues to scrub themusic track, as shown sequentially in FIG. 5II, where the subsequentpresentation position of the music track is 0:45, rather than 0:36. Inresponse to detecting a rightward swipe gesture 539 from initialposition 540-1 to position 540-2, the device 100 increases the scrubbingspeed of the music track, as shown sequentially in FIG. 5JJ, where thesubsequent presentation position of the music track is 1:05, rather than0:55 (e.g., the presentation position of the music track as a result oftap gesture 538-2 rather than rightward swipe gesture 539).

FIGS. 5KK-5LL illustrate example user interfaces for transitioning froma lock screen of the device 100 to the second media player userinterface. In FIG. 5KK, the device 100 displays a lock screen userinterface. The device 100 detects a rightward swipe gesture 541 frominitial position 542-1 to position 542-2. In some embodiments, inresponse, the device 100 displays the second media player userinterface, as shown in FIG. 5LL.

FIGS. 5MM-5OO illustrate example user interfaces for using a secondmedia player user interface on a lock screen. In FIG. 5MM, the device100 displays the second media player user interface on a lock screen ofthe device 100. Subsequently, the device 100 detects a tap gesture 543-1that exceeds a light press threshold IT_(L) and remains below a deeppress intensity threshold ITS, as shown in FIG. 5NN. In response, thedevice 100 toggles to playing the music track Song No. 1 by Band No. 1,as shown in FIG. 5OO.

FIGS. 6A-6C are flow diagrams depicting a method 600 for media playbackcontrol using intensity-based input, in accordance with someembodiments. Although some of the examples which follow will be givenwith reference to inputs on a touch-sensitive display (in which atouch-sensitive surface and a display are combined), in someembodiments, the device detects inputs on a touch-sensitive surface 450that is separate from the display 451, as shown in FIG. 4B. Someoperations in method 600 are, optionally, combined and/or the order ofsome operations is, optionally, changed.

As described below, the method 600 reduces the number, extent, and/ornature of the inputs from a user and produce and more efficienthuman-machine interface, thereby providing users with easy-to-use andintuitive ways to control media playback. For battery-operatedelectronic devices, allowing for efficient, seamless control of mediaplayback conserves power and increases the time between battery charges(e.g., by reducing the requirement for extensive and inefficient userinteractions that drain battery power).

At an electronic device with a touch-sensitive surface, a display, andone or more sensors to detect intensities of contacts on thetouch-sensitive surface, while media (e.g., audio, video, and/or images)is playing on the device, the device detects (602) a first input (e.g.,a tap gesture 510-1 as shown in FIG. 5C) that includes detecting acontact at a location on the touch-sensitive surface that is associatedwith a first media playback control (e.g., player icon 512 b as shown inFIG. 5C) (e.g., detect an input by a contact on a touch-sensitivedisplay while the contact is at an icon or at an area that correspondsto the first media playback control, or detect an input by a contact ona touch-sensitive surface while a cursor or other location marker is atthe icon or at the area that corresponds to the first media playbackcontrol on the display).

In response to detecting the first input, in accordance with adetermination that the first input is detected while the device isoperating in a first media playback mode of operation, the deviceperforms (604) a media playback operation (e.g., play a music track)associated with the first media playback control (e.g., play icon 512 b,as shown in FIG. 5D) when a characteristic intensity of the firstcontact remains below a first intensity threshold (e.g., a hintthreshold, a light press threshold or a deep press threshold).

In response to detecting the first input, in accordance with adetermination that the first input (e.g., tap gesture 510-2 as shown inFIG. 5G) is detected while the device is operating in a second mediaplayback mode of operation, distinct from the first media playback modeof operation, and that the input meets first control-activation criteriathat include a criterion that is met when a characteristic intensity ofthe contact exceeds the first intensity threshold during the firstinput, the device performs (606) the media playback operation (e.g.,video presented via the display, music presented with speakers builtinto the electronic device, as shown in 5H, or music presented withremote (e.g., wireless) speakers that communicate with the electronicdevice) associated with the first media playback control.

In response to detecting the first input, in accordance with adetermination that the first input (e.g., tap gesture 510-3 as shown inFIG. 5I) is detected while the device is operating in the second mediaplayback mode of operation and that the input does not meet the firstcontrol-activation criteria that include the criterion that is met whenthe characteristic intensity of the contact exceeds the first intensitythreshold during the first input, the device continues (608) to play themedia on the device without performing the media playback operationassociated with the first media playback control (e.g., as shown inFIGS. 5I-5J).

Providing two different media playback mode enhances the operability ofthe device. Having one mode with easier-to-select playback controlsbased on input intensity enhances the operability of the device andmakes the user-device interface more efficient by helping the user toprovide proper inputs and reducing user mistakes whenoperating/interacting with the device, even without the user having toview the display.

In some embodiments, the electronic device is (610) in an unlocked statein the first media playback mode of operation (e.g., as shown in FIG.5C), and the electronic device is in a locked state in the second mediaplayback mode of operation (e.g., as shown in FIG. 5OO). In someembodiments, the locked state prevents access to most, if not all, ofthe applications on the electronic device, except a media playerapplication. In some embodiments, the unlocked state permits access tomost, if not all, of the applications on the electronic device,including the media player application.

Including a second media playback mode of operation that operates in alocked state provides the user with improved media playbackfunctionality that enhances the operability of the device. For example,accessing playback functionality from a locked state makes theuser-device interface more efficient by helping the user to consume andnavigate media content without having to unlock the device.

In some embodiments, an icon that corresponds to the first mediaplayback control is not displayed (612) on the display in the secondmedia playback mode of operation (e.g., as represented by zones 518a-518 c shown in FIG. 5F, which do not display playback controls).

In some embodiments, the device detects (614) a second input thatincludes detecting a second contact at a second location on thetouch-sensitive surface. In some embodiments, the second contact makes atap gesture (e.g., tap gesture 509-1 as shown in FIG. 5B). In someembodiments, the second contact makes a swipe gesture from a predefinededge of the touch-sensitive surface (e.g., rightward swipe gesture 511-2as shown in FIG. 5K). In response to detecting the second input, inaccordance with a determination that the second input meets first mediaplayback mode selection criteria that include a criterion that is metwhen a characteristic intensity of the second contact remains below asecond intensity threshold (e.g., a light press or deep press threshold)during the second input, the device operates in the first media playbackmode of operation (e.g., as shown in FIGS. 5B-5C). In response todetecting the second input, in accordance with a determination that thesecond input meets second media playback mode selection criteria thatinclude a criterion that is met when the characteristic intensity of thesecond contact exceeds the second intensity threshold during the secondinput, the device operates in the second media playback mode ofoperation (e.g., as shown in FIGS. 5E-5F). In some embodiments, thefirst input and the second input are the same input. In someembodiments, the second input occurs prior to the first input.

Providing a user with the capability to selectively transition to afirst media playback mode or a second media playback mode of operationusing a single user input enhances the operability of the device. Forexample, allowing a user to transition to a media playback mode using asingle user input makes the user-device interface more efficient (e.g.,by helping the user to provide proper inputs and reducing user mistakeswhen operating/interacting with the device) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

In some embodiments, the device displays (616) icons that correspond tomedia playback controls (e.g., icons 512 a-512 c as shown in FIG. 5D) onthe display when the electronic device is operating in the first mediaplayback mode of operation and foregoes display of icons that correspondto media playback controls on the display when the electronic device isoperating in the second media playback mode of operation (e.g., as shownin FIG. 5F).

In some embodiments, in response to detecting the first input, inaccordance with a determination that the first input is detected whilethe device is operating in the first media playback mode of operation,the device visually distinguishes (620) an icon that corresponds to thefirst media playback control (e.g. by highlighting and/or enlarging theicon, as shown in FIG. 5S-5T) to indicate that the first media playbackcontrol has been activated. In response to detecting the first input, inaccordance with a determination that the first input is detected whilethe device is operating in the second media playback mode of operation,the device visually distinguishes an area of the display that isproximate to a location on the display that corresponds to the locationof the contact on touch-sensitive surface (e.g. by highlighting the areaon the display, independent of whether an icon that corresponds to thefirst media playback control is displayed in the area, as shown in FIGS.5U and 5W, or by providing haptic feedback, as shown in FIGS. 5U-5V) toindicate that the first media playback control has been activated.

Providing visual feedback in response to a user activation of an icon oran area of a display provides the user with feedback about an activationdetected by the device and provides visual feedback to the userindicating that pressing at an icon or an area of a display will causethe device to perform an operation associated with the user interfaceelement. Providing improved visual feedback to the user enhances theoperability of the device and makes the user-device interface moreefficient (e.g., by helping the user to provide proper inputs andreducing user mistakes when operating/interacting with the device)which, additionally, reduces power usage and improves battery life ofthe device by enabling the user to use the device more quickly andefficiently.

In some embodiments, in response to detecting the first input, inaccordance with a determination that the first input is detected whilethe device is operating in the second media playback mode of operationand that the first input meets the first control-activation criteriathat include a criterion that is met when the characteristic intensityof the contact does not exceed a second intensity threshold, greaterthan the first intensity threshold (e.g., light press threshold or adeep press threshold), during the first input, the device performs (622)a discrete media playback operation (e.g., a discrete operation such asplay, pause, skip to next media in an ordered list of a plurality ofmedia, or skip to previous media in an ordered list of the plurality ofmedia) associated with the first media playback control (e.g., as shownin FIGS. 5X-5Y). In response to detecting the first input, in accordancewith a determination that the first input is detected while the deviceis operating in the second media playback mode of operation and that thefirst input meets second control-activation criteria that include acriterion that is met when the characteristic intensity of the contactexceeds the second intensity threshold during at least part of the firstinput, the device performs a continuous media playback operation (e.g.,a continuous operation such as fast forward or rewind through thecurrent media, based on the intensity of the contact or lateral movementof the contact) associated with the first media playback control(instead of performing a discrete media playback operation) (e.g., asshown in FIGS. 5Z-5BB).

Performing a discrete or continuous operation based on a single userinput provides the user with more efficient user-device interface andthereby enhances operability.

In some embodiments, the device displays (624) a scrubber bar (e.g.,524-1 shown in FIG. 5AA) when the characteristic intensity of thecontact exceeds the second intensity threshold. For example, when thecharacteristic intensity initially meets or exceeds the second intensitythreshold during the first input, the electronic device performs a fastforward or rewind operation on the currently playing media and alsodisplays a scrubber bar until the first input ends (e.g., as shown inFIGS. 5Z-5BB).

Displaying a scrubber bar in response to a user input with certaincharacteristics provides the user with visual feedback about how thedevice is navigating the content media and thereby provides moreefficient use of the device and enhances operability. Displaying thescrubber bar enhances the operability of the device and makes theuser-device interface more efficient (e.g., by avoiding display duringinadvertent user inputs and by being displayed during intentional userinputs that meet certain intensity criteria) which, additionally,reduces power usage and improves battery life of the device by enablingthe user to use the device more quickly and efficiently.

In some embodiments, while the electronic device is operating in thefirst media playback mode of operation, the device displays (626) afirst media player user interface on the display, wherein: the firstmedia player user interface includes a first media player transportcontrol icon (e.g., rewind icon 512 a, player icon 512 b, fast-forwardicon 512 c as shown in FIG. 5C) that corresponds to the first mediaplayback control. The first media player transport control iconcorresponds to a first area of the touch-sensitive surface that, whenactivated, causes the electronics device to perform the media playbackoperation associated with the first media playback control (e.g.,rewind, play, fast-forward). While the electronic device is operating inthe second media playback mode of operation, the device displays asecond media player user interface on the display, distinct from thefirst media player user interface. The second media player userinterface includes a media player transport control zone (e.g., rewindzone 518 a, player zone 518 b, fast-forward zone 518 c as shown in FIG.5F) associated with the first media playback control. The media playertransport control zone corresponds to a second area of thetouch-sensitive surface, larger than the first area of thetouch-sensitive surface, that, when activated, causes the electronicdevice to perform the media playback operation (e.g., rewind, play,fast-forward) associated with the first media playback control. In someembodiments, the first area and the second area are hit regions for thefirst media playback control in the first media playback mode ofoperation and the second media playback mode of operation, respectively,and the hit region is larger in the second media playback mode ofoperation. In some embodiments, a plurality of media player zones in thesecond media playback mode of operation cover substantially the entiredisplay, with each zone corresponding to a separate portion of thedisplay (e.g., a top third, middle third, and bottom third; or a leftthird, center third, and right third). In some embodiments, the mediaplayer transport control zones in the second media playback mode ofoperation comprise three zones, such as a first zone for transitioningbackwards through a media content item (e.g., a song) at an acceleratedrate or switching to a previous media content item in a list of mediacontent items; a second zone for moving forwards through the mediacontent item at a normal rate or pausing the media content item; and athird zone for transitioning forwards through the media content item atan accelerated rate or switching to a next media content item in thelist of media content items.

By associating a media playback control with a zone that is larger thana region of an icon, the user can more easily select a media playbackcontrol. Easier media playback control enhances the operability of thedevice and makes the user-device interface more efficient (e.g., byhelping the user to provide proper inputs and reducing user mistakeswhen operating/interacting with the device) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

In some embodiments, the processing unit 710 is configured to enabledisplay (e.g., via enabling unit 718) of a scrubber bar when thecharacteristic intensity of the contact exceeds the second intensitythreshold.

In some embodiments, while the electronic device is operating in thefirst media playback mode of operation, the processing unit 710 isconfigured to enable display (e.g., via enabling unit 718) of a firstmedia player user interface on the display unit 702. In someembodiments, the first media player user interface includes a firstmedia player transport control icon that corresponds to the first mediaplayback control.

FIGS. 8A-8C are flow diagrams depicting a method 800 for media playbackcontrol using intensity-based input, in accordance with someembodiments. Although some of the examples which follow will be givenwith reference to inputs on a touch-sensitive display (in which atouch-sensitive surface and a display are combined), in someembodiments, the device detects inputs on a touch-sensitive surface 450that is separate from the display 451, as shown in FIG. 4B. Someoperations in method 800 are, optionally, combined and/or the order ofsome operations is, optionally, changed.

As described below, the method 800 reduces the number, extent, and/ornature of the inputs from a user and produce and more efficienthuman-machine interface, thereby providing users with easy-to-use andintuitive ways to control media playback. For battery-operatedelectronic devices, allowing for efficient, seamless control of mediaplayback conserves power and increases the time between battery charges(e.g., by reducing the requirement for extensive and inefficient userinteractions that drain battery power).

At an electronic device with a touch-sensitive surface, a display, andone or more sensors to detect intensities of contacts on thetouch-sensitive surface, the device displays (802) a first userinterface on the display, wherein the first user interface includes amedia player affordance (e.g., play icon 502 a in FIG. 5A). In someembodiments, the first user interface also displays a list of mediacontent items (e.g., music tracks as shown in FIG. 5A) available forplayback using the electronic device.

The device detects (804), on the touch-sensitive surface, a first inputby a first contact that corresponds to a focus selector at the mediaplayer affordance (e.g., detect an input by a contact on atouch-sensitive display while the contact is at the media playeraffordance (such as tap gesture 509-1 or 509-2 in FIGS. 5B and 5E,respectively), or detect an input by a contact on a touch-sensitivesurface while a cursor or other location marker is at the media playeraffordance on the display).

In response to detecting the first input by the first contact thatcorresponds to the focus selector at the media player affordance, inaccordance with a determination that the first input meets one or morefirst media player selection criteria, wherein the first media playerselection criteria include a criterion that is met when a characteristicintensity of the first contact remains below a first intensity threshold(e.g., below a “light press” or “deep press” intensity threshold), thedevice displays (806) a first media player user interface on the display(e.g., as shown in FIG. 5C), wherein the first media player userinterface includes a plurality of media player transport control icons(e.g., icons to play, pause, skip to next media content item, skip toprevious media content item, and/or scrub a media content item) that,when activated, control playback of media (e.g., audio, video, and/orimages) presented using the electronic device (e.g., music presentedwith speakers built into the electronic device or music presented withremote (e.g., wireless) speakers that communicate with the electronicdevice).

In response to detecting the first input by the first contact thatcorresponds to the focus selector at the media player affordance, inaccordance with a determination that the first input meets one or moresecond media player selection criteria, wherein the second media playerselection criteria include a criterion that is met when thecharacteristic intensity of the first contact exceeds the firstintensity threshold (e.g., the contact intensity goes above a “lightpress” or “deep press” intensity threshold, at least momentarily), thedevice displays (808) a second media player user interface on thedisplay (e.g., as shown in FIG. 5F), distinct from the first mediaplayer user interface, wherein the second media player user interfaceincludes a plurality of media player transport control zones (e.g.,predefined areas on the touch-sensitive surface associated with play,pause, skip to next media content item, skip to previous media contentitem, and/or scrub media content item functions) that, when activated,control playback of media presented using the electronic device. In someembodiments, the plurality of media player zones cover substantially theentire display, with each zone corresponding to a separate portion ofthe display (e.g., a top third, middle third, and bottom third; or aleft third, center third, and right third). In some embodiments, themedia player transport control zones comprise three zones, such as afirst zone for transitioning backwards through a media content item(e.g., a song) at an accelerated rate or switching to a previous mediacontent item in a list of media content items; a second zone for movingforwards through the media content item at a normal rate or pausing themedia content item; and a third zone for transitioning forwards throughthe media content item at an accelerated rate or switching to a nextmedia content item in the list of media content items.

Providing a user with the capability to selectively transition to afirst media playback mode or a second media playback mode of operationusing a single user input enhances the operability of the device andmakes the user-device interface more efficient (e.g., by helping theuser to provide proper inputs and reducing user mistakes whenoperating/interacting with the device).

In some embodiments, while presenting one of the first media player userinterface and the second media player user interface, the device detects(810), on the touch-sensitive surface, a second input by a secondcontact. In response to detecting the second input by the secondcontact, and, in accordance with a determination that the second inputmeets one or more media player switching criteria, the device switchesto present the other one of the first media player user interface andthe second media player user interface (e.g., as shown in FIGS. 5O-5P).

Toggling between media player user interfaces using a single inputenhances the operability of the device and makes the user-deviceinterface more efficient (e.g., by helping the user to provide properinputs and reducing user mistakes when operating/interacting with thedevice).

In some embodiments, the media player switching criteria include (812) acriterion that is met when the second input by the second contact is aswipe gesture (e.g., a rightward swipe gesture 530-1 to 530-2, as shownin FIG. 5O).

In some embodiments, the media player switching criteria include (814) acriterion that is met when the second input by the second contact is atap gesture.

In some embodiments, the device detects (816), on the touch-sensitivesurface, a third input by a third contact that corresponds to the focusselector at a first media player transport control zone in the secondmedia player user interface (e.g., detect an input by a contact on atouch-sensitive display while the contact is at the first media playertransport control zone, or detect an input by a contact on atouch-sensitive surface while a cursor or other location marker is atthe first media player transport control zone on the display). Inresponse to detecting the third input by the third contact, and, inaccordance with a determination that the third input meets one or morezone activation criteria, wherein the zone activation criteria include acriterion that is met when a characteristic intensity of the thirdcontact exceeds an intensity threshold (e.g., above a “light press” or“deep press” intensity threshold), the device activates a medianavigation function that corresponds to the first media player transportcontrol zone; and the device provides haptic feedback to indicate thatthe first media player transport control zone has been activated (e.g.,as shown in FIGS. 5U-5V).

Providing tactile feedback in response to a user selection of an icon orarea of a display provides the user with feedback about a selectiondetected by the device and indicates that pressing at the icon or areaof a display caused the device to perform an operation associated withthe user interface element. Providing tactile feedback to the userenhances the operability of the device and makes the user-deviceinterface more efficient (e.g., by helping the user to provide properinputs and reducing user mistakes when operating/interacting with thedevice).

In some embodiments, the device detects (818), on the touch-sensitivesurface, a fourth input by a fourth contact that corresponds to thefocus selector at a first media player transport control zone in thesecond media player user interface (e.g., detect an input by a contacton a touch-sensitive display while the contact is at the first mediaplayer transport control zone, or detect an input by a contact on atouch-sensitive surface while a cursor or other location marker is atthe first media player transport control zone on the display). In someembodiments, the fourth input and the third input are the same input bythe same contact. In response to detecting the fourth input by thefourth contact, and, in accordance with a determination that the fourthinput meets one or more zone activation criteria, wherein the zoneactivation criteria include a criterion that is met when acharacteristic intensity of the fourth contact exceeds an intensitythreshold (e.g., above a “light press” or “deep press” intensitythreshold), the device activates a media navigation function thatcorresponds to the first media player transport control zone; and thedevice provides visual feedback to indicate that the first media playertransport control zone has been activated (e.g., displaying a shape,such as a white, black, or colored circle within the first media playercontrol zone, proximate to the focus selector in some embodiments)(e.g., as shown in FIGS. 5U and 5W).

Providing visual feedback in response to a user selection of an icon orarea of a display provides the user with feedback about a selectiondetected by the device and indicates that pressing at the icon or areaof a display caused the device to perform an operation associated withthe user interface element. Providing visual feedback to the userenhances the operability of the device and makes the user-deviceinterface more efficient (e.g., by helping the user to provide properinputs and reducing user mistakes when operating/interacting with thedevice).

In some embodiments, while displaying the second media player userinterface and presenting a first media content item, the device detects(820), on the touch-sensitive surface, a fifth input by a fifth contactthat corresponds to the focus selector at a first media player transportcontrol zone in the second media player user interface (e.g., detect aninput by a contact on a touch-sensitive display while the contact is atthe first media player transport control zone, or detect an input by acontact on a touch-sensitive surface while a cursor or other locationmarker is at the first media player transport control zone on thedisplay). In response to detecting the fifth input by the fifth contact,in accordance with a determination that the fifth input meets one ormore next-item criteria, wherein the next-item criteria include acriterion that is met when a characteristic intensity of the contactremains below a second intensity threshold (e.g., below a “deep press”intensity threshold), the device transitions from presenting the firstmedia content item to presenting a second media content item (e.g., anext media content item associated with a media playlist) (e.g., asshown in FIGS. 5X-5Y). In response to detecting the fifth input by thefifth contact, in accordance with a determination that the fifth inputmeets one or more scrubbing criteria, wherein the scrubbing criteriainclude a criterion that is met when a characteristic intensity of thecontact exceeds the second intensity threshold (e.g., above a “deeppress” intensity threshold), the device scrubs through the first mediacontent item (e.g., scrubbing at a rate that is greater than a normalplayback speed) (e.g., as shown in FIGS. 5Z-5BB). In some embodiments, ascrubber bar (e.g., scrubber bar 524-1 in FIG. 5AA) is temporarilydisplayed during scrubbing in the second media player user interface. Insome embodiments, the scrubbing rate increases as the intensity of thecontact increases above the second intensity threshold. In someembodiments, after an initial deep press by a contact, if the contactmoves towards an edge of the display, the scrubbing rate increases asthe contact moves laterally across the touch sensitive surface, awayfrom the location of the initial deep press by the contact. For example,as shown in FIG. 5CC, the scrubbing speed increases as a contact 536-3moves laterally across the screen, from initial position 537-1 toposition 537-2.

Performing conditional actions based on a single user input enhances theoperability of the device and makes the user-device interface moreefficient (e.g., by reducing the number of user inputs to performdifferent actions and thereby reduce user mistakes whenoperating/interacting with the device) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

In some embodiments, while displaying the second media player userinterface and presenting a first media content item, the device detects(822), on the touch-sensitive surface, a sixth input by a sixth contactthat corresponds to the focus selector at a second media playertransport control zone in the second media player user interface (e.g.,detect an input by a contact on a touch-sensitive display while thecontact is at the second media player transport control zone, or detectan input by a contact on a touch-sensitive surface while a cursor orother location marker is at the second media player transport controlzone on the display). In response to detecting the sixth input by thesixth contact, in accordance with a determination that the sixth inputmeets one or more play/pause criteria, wherein the play/pause criteriainclude a criterion that is met when a characteristic intensity of thecontact remains below a second intensity threshold (e.g., below a “deeppress” intensity threshold), the device toggles between playing andpausing the first media content item (e.g., as shown in FIGS. 5DD-5GG).In response to detecting the sixth input by the sixth contact, inaccordance with a determination that the second input meets one or morescrubbing criteria, wherein the scrubbing criteria include a criterionthat is met when a characteristic intensity of the contact exceeds thesecond intensity threshold (e.g., above a “deep press” intensitythreshold), the device scrubs through the first media content item(e.g., scrubbing at a rate that is greater than a normal playback speed)(e.g., as shown in FIGS. 5HH-5II). In some embodiments, a scrubber bar(e.g., scrubber bar 524-2 in FIG. 5II) is temporarily displayed duringscrubbing in the second media player user interface. In someembodiments, the scrubbing rate increases as the intensity of thecontact increases above the second intensity threshold. In someembodiments, after an initial deep press by a contact, if the contactmoves towards an edge of the display, the scrubbing rate increases asthe contact moves laterally across the touch sensitive surface, awayfrom the location of the initial deep press by the contact. For example,as shown in as shown in FIG. 5JJ, the scrubbing speed increases as acontact 539 moves laterally across the screen, from initial position540-1 to position 540-2.

Performing conditional actions based on a single user input enhances theoperability of the device and makes the user-device interface moreefficient (e.g., by reducing the number of user inputs to performdifferent actions and thereby reduce user mistakes whenoperating/interacting with the device) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

In some embodiments, the device is (824) locked. While the electronicdevice is locked, the device displays a lock-screen user interface onthe display and detects, on the touch-sensitive surface, a seventh inputby a seventh contact while displaying the lock-screen user interface(e.g., detecting a rightward swipe gesture of contact 541 from initialposition 542-1 to position 542-2, as shown in FIG. 5KK). In response todetecting the seventh input by the seventh contact, the device displaysthe second media player user interface (e.g., as shown in FIG. 5LL).While displaying the second media player user interface, the devicedetects an eighth input by an eighth contact that corresponds to thefocus selector at a respective media player transport control zone inthe second media player user interface (e.g., detect an input by acontact on a touch-sensitive display while the contact is at therespective media player transport control zone, or detect an input by acontact on a touch-sensitive surface while a cursor or other locationmarker is at the respective media player transport control zone on thedisplay). In response to detecting the eighth input by the eighthcontact, and, in accordance with a determination that the eighth inputmeets one or more zone activation criteria, wherein the zone activationcriteria include a criterion that is met when a characteristic intensityof the contact exceeds an intensity threshold (e.g., above a “lightpress” or “deep press” intensity threshold), activating a medianavigation function (e.g., play, pause, skip to next media content item,skip to previous media content item, or scrub media content item) thatcorresponds to the respective media player transport control zone (and,in some embodiments, providing haptic and/or visual feedback to indicatethat the respective media player transport control zone has beenactivated) (e.g., as similarly shown in FIGS. 5FF-5GG).

Displaying a second media playback mode of operation that operates in alocked state after a user-selection provides the user with improvedmedia playback functionality that enhances the operability of thedevice. For example, accessing playback functionality from a lockedstate makes the user-device interface more efficient by helping the userto consume and navigate media content without having to unlock thedevice and provide access to other applications or potentiallycompromise personal data on the device.

In some embodiments, the device is (826) locked. While the electronicdevice is locked: the device displays a lock-screen user interface onthe display, the lock-screen user interface including the second mediaplayer user interface. While displaying the second media player userinterface, the device detects an ninth input by a ninth contact thatcorresponds to the focus selector at a respective media player transportcontrol zone in the second media player user interface (e.g., detect aninput by a contact on a touch-sensitive display while the contact is atthe respective media player transport control zone, or detect an inputby a contact on a touch-sensitive surface while a cursor or otherlocation marker is at the respective media player transport control zoneon the display). In response to detecting the ninth input by the eighthcontact, and, in accordance with a determination that the ninth inputmeets one or more zone activation criteria, wherein the zone activationcriteria include a criterion that is met when a characteristic intensityof the contact exceeds an intensity threshold (e.g., above a “lightpress” or “deep press” intensity threshold), the device activates amedia navigation function (e.g., play, pause, skip to next media contentitem, skip to previous media content item, or scrub media content item)that corresponds to the respective media player transport control zone(and, in some embodiments, providing haptic and/or visual feedback toindicate that the respective media player transport control zone hasbeen activated) (e.g., as shown in FIGS. 5MM-5OO).

Including a second media playback mode of operation that operates in alocked state provides the user with improved media playbackfunctionality that enhances the operability of the device. For example,accessing playback functionality from a locked state makes theuser-device interface more efficient by helping the user to consume andnavigate media content without having to unlock the device and provideaccess to other applications or potentially compromise personal data onthe device.
